CONTAINER.

Application led November 3, 1926. Serial No. 145,945.

The invention relates to containers and it is particularly directed to self sealing and vented cans for containing milk, cream and other products. y

In theshipment of milk and cream in the dairy industry and the shipment of other commodities in many other industries, it is desirable to provide as sanitary a can as is possible combined with strength and durability and for economy in transportation it is desirable that the cans may be stacked one upon the other in upright position. It is also advantageous to provide a cover or lid for the can that Will not leak nor loosen in handling r and at the same time provide means for venting the can in the event of an accumulation of gaseous pressure Within the can. y

The object of the present invention is to provide a container which shall have among others the advantages above set forth.

The invention is illustrated inthe accompanying drawings, in Which- Figure 1 is an 'elevational view of a fraction of a container having the invention applied thereto; Fig. 2 a plan view of the same; Fig. 3 an enlarged cross-section on line 3-3 of Fig. 2; Fig. 4 a plan view of a modifica-tion of the venting device and Fig. 5 a longitudinal cross section of the latter device.

In the illustrative embodiment of the invention the receptacle 1 is formed of selected material and in desired shape, the receptacle illustrated having a neck 2 at its upper end. A reinforcingband 3 surrounds and is secured to the neck 2 adjacent to the mouth of the receptacle, and secured to this band is a selected number of bifurcated brackets 4, the bifurcated portion of each bracket extending outwardly from the band. Thesebrackets are designed to receive the lower ends of the bolts 5 that are pivoted at their upper ends to the plates 6 that are secured to the upper side of the cover 7. Each plate 6 projects laterally beyond the edge of the cover and the bolts 5 are pivoted to these projecting ends,

The cover 7 is preferably stamped out of sheet meta-l, the plates 6 being spot welded to it. The sheet is bent upon itself to form an annular cavity 8 for the reception of a gasket` 9 and of the upper end of the neck or top of the receptacle. The contacting portions of the sheet form a double wall about the top or rim of the receptacle and the portions of the sheet below the gasket space assure the retention of the cover upon the receptacle when the bolts are engaged in the brackets 4 and the Wing nuts 10 are tightened against the brackets. Each Wing nut may be apertured at 11 and the bolts 5 may be similarly apertured for the reception of the commonly used seal 11 to seal the nuts to the bolts respectively.

The top 12 of the cover is dished or concaved somewhat and an aperture 13 is formed in the central portion thereof. A casing 14: is secured to the top 12 and is suspended through the aperture 13. A port 15 is formed in the bottom of the casing and a valve 16 normally closes the port under the influence of a springr 17 that is disposed between the valve and a hollon7 plug 18 that is externally threaded and engages the threads formed in the wall of a port or opening 19 formed in the top of the casing 14. A series of ports 20 is formed v in the Wall of the plug which establish communication between the interior of the plug and the interior of the casing. A screen 21 is suitably supported Within the plug and above the ports 20. The upper portion 22 of the opening in the plug is hexagonal so that the plug may be removed and inserted. Preferably this portion of the o-pening should have such form that a special tool would be required to remove the plug. As a further protection against unauthorized removal of the plug, ap'ertured lugs 23, 24 may be formed on the plug and the casing respectively for the reception of a seal 25.

In Figs. 4 and 5 I secure a casing 26 in the central aperture 13 in the lid, the casing having a` port 27 therein adapted to be normally closed by a valve 28 that is secured to one end of a suitable spring 29, the other end of the spring being' secured to theI casing. A cover plate 30 may be loosely secured to the casing over the valve 2S so that unauthorized access to the valve will be avoided.

The lid or cover 7 is readily attached to the receptacle and locked thereto by the bolts, the gasket making a fluid tight joint between them. The valve Will retain its seat at all times 'except when any pressure Within the receptacle is sui'licient to overcome the spring, the tension of which is predetermined. When the valve is caused to unseat the receptacle is vented and no harm is done to the receptacle nor to the user by any excessive pressure Within the receptacle.

What I claim is 1. The combination, with an open top receptacle, of a lid adapted to receive the mouth of the receptacle, cooperating means on the. lid and on the receptacle for locking` and sealing the lid to the receptacle, a vent in the lid and a yspring opposed valve below the lid and normally closing the venty and adapted to open the same under the inliuence of an accumulation of pressure Within the. receptacle.

2. A milk can consisting of an open top receptacle, a lid adapted to seat about the mouth of the receptacle and having a dished top, locking means pivotally carried by the lid, means carried by the receptacle and adapted to be engaged by the locking means for securing the lid to the receptacle, a vent in the central portion of the dished top, a hollow casing secured to the said top and depending thro ugh the vent and a valve within the casing and normally closing the same against the passage of the contents o1 the receptacle through the vent.

3. The combination with a receptacle having an open mouth, ailid adapted to close the said mouth, means to lock the lid to the receptacle, the lid having an aperture in its top, an open top and bottom casing secured to the lid and depending through the aperture, a hollow plug removably secured in the casing and having apertures therein to form a communication between the casing and the plug, a Valve adapted to seat in the open bottom of the casing and a resilient member normally holding the valve on its seat.

' In witness whereof I have hereunto signed my name this 27th day of October, 1925.
